No hot wiring, this sensor light controlled cover plate fits most traditional plug boxes with simple one-screw installation by replacing the existing cover plate. Ever want auto night lights in specific rooms or locations that do not interfere with dual plug outlets? This is the solution for you, unlike most other competitors, this unit comes with an on/off switch. Light sensor triggers turn on as darkness occurs and off as more natural light becomes available. Under normal conditions it's a 20 to 45 second installation.
